  • First

    First
    First electric battery invented by Alessandro Volta. Volta proved that electricity could travel over wires.

  • Christian Oersted

    Christian Oersted
    Relationship of electricity and magnetism confirmed by Hans Christian Oersted who observed that electrical currents effected the needle on a compass and Marie Ampere, who discovered that a coil of wires acted like a magnet when a current is passed thorough it.
    D. F. Arago invented the electromagnet.

  • Ohms Law

    Ohms Law
    Georg Ohm (Germany) defined the relationship between power, voltage, current and resistance in Ohms Law.

  • Michael

    Michael
    Using his invention the induction ring, Michael Faraday (England) proved that electricity can be induced (made) by changes in an electromagnetic field. Faraday's experiments about how electric current works led to the understanding of electrical transformers and motors.

  • Willam Stanley

    Willam Stanley
    William Stanley develops transformer and Alternating Current electric system. Frank Sprague builds first American transformer and demonstrates use of step up and step down transformers for long distance AC power transmission in Great Barrington, Massachusetts. The Westinghouse Electric Company is organized. 40 to 50 water powered electric plants reported on line or under construction in the U.S. and Canada.

  • Tesla

    Tesla
    Nikola Tesla (U.S. immigrant from Austrian Empire) demonstrated the first polyphase alternating current (AC) electrical system. His AC system included all units needed for electricity production and use: generator, transformers, transmission system, motor (used in appliances) and lights. George Westinghouse, the head of Westinghouse Electric Company, bought the patent rights to the AC system.

  • Electron

    Electron
    Electron discovered by J. J. Thomson.

  • Albert Einstein

    Albert Einstein
    Albert Einstein publishes his special theory of relativity and his theory on the quantum nature of light, which he identified as both a particle and a wave. With ever new appliances, electricity begins to transform everyday life.

  • Use of Electricity

    Use of Electricity
    Scientists’ understanding of the structure of the atom and of its component particles grows, the phone and radio become common, and the modern television is born.

  • Discovery of Electrons

    Discovery of Electrons
    Ernest R. Rutherford measured the distribution of an electric charge within the atom.
